Carlsons Sporting Clays Choke Tube Features The Carlsons Sporting Clays Choke Tube is precision machined from 17-4 stainless steel giving it a bright stainless finish that resists corrosion while holding tight manufacturing tolerances. This stainless construction is built to produce a choke tube that patterns more consistently than standard factory options an advantage clay shooters and hunters both value. A 25% longer parallel section inside the choke throws denser more consistent patterns than conventional flush mount choke tubes improving performance at the distances sporting clays and upland birds are typically engaged. The design accommodates lead shot steel shot copper plated shot nickel shot Hevi-Shot and buck shot giving shooters flexibility across load types. A knurled end on the choke tube allows for quick and easy removal or installation without requiring a dedicated tool for routine changes between rounds. The constriction value is lasered directly onto the tube giving shooters an easy visual reference when swapping chokes in the field or at the range. Built specifically for .410 GA Stevens 301 shotguns this choke tube is matched to that platform s thread pattern for a secure reliable fit. For shooters seeking a dependable higher-performing choke upgrade for their Stevens 301 the Carlsons Sporting Clays Modified Choke Tube is available for sale at GrabAGun.
